LOCK FOR FLUSHING-VALVES SPECIFICATION forming part of Letters Patent No. 594,709, dated November 30, 1897. Application filed May 2, 1896. Serial No. 589,970. (No model.)

To all whom it may concern.- 7

Be it known that 1, CHARLES H. SHEPHERD, of New York city, in the countyand State'of New York, have invented a new and Improved Lock for Flushing-Valves, of which the following is a full, clear, and exact description.

In ordinary flushing-tanks used in watercloset bowls the Water flows through the flushing-pipe so long as the valve is held in an elevated position, but when the valve-lever is released the valve closes and the flushing ceases. When the apparatus is used by persons who do not appreciate the value of thorough flushing, the valve is raised by a quick pull of the handle and the flushing is not properly done. To obviate this difficulty is the object of my invention.

My invention consists in the combination, with the flushing-valve lever, of a lock which engages the said lever when it is raised and holds it in an elevated position until released by the descent of the float-ball of the supplyvalve.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in both views.

Figure 1 is a vertical transverse section of a flushing-tank, showing the application of my improvement; and Fig. 2 is an enlarged detail view of the flushing-valve lock.

The flushing-tank A is connected with the pipe 13, which leads to the water-closet bowl, and the upper end of the pipe B is provided with a valve-seat a, to which is fitted the.

flushing-valve 17, provided with the overflowtube a, which opens into the pipe B and extends upwardly to the water-line. c is provided with a cross-bar d, with which is connected a rod 8, pivotally connected to one end of a lever O, the other end being provided with an operating-cord fin the usual way, the lever being fulcrumed at the top of the side wall of the tank.

The supply-pipe D enters the opposite side of the tank and is provided with a ball-cock g, of the usual description, furnished with an angledfloat-lever h, carrying at its free end a float i.

To an arm E, attached to the side of the tank, is affixed the lock F, which is designed to hold the lever G in an elevated position.

The tube The lock F is formed of a base-plate j, which is secured to the arm E, a right-angled lever G, pivoted on a screw is, entering the plate j, and a spring-pressed catch Z, pivoted on the screw m, which also enters the plate j. The shorter arm of the right-angled lever G is bent twice at right angles, forming the upwardlyturned hook n, and the hook end of the catch l is adapted to engage the hook at of the lever, and the opposite end of the lever is perforated to receive a chain 0, which is connected with the float-lever h. The longer arm of the lever G extends over the top of the arm 0 and passes through an eye 19, attached to the said arm. 0. The eye 19 is attached to a short bar, andthe said bar is fastened to the lever O by a binding of soft wire, as shown.

When the lever O is operated by pulling the cord f, the lever G is raised, and the hook n of the shorter arm of this lever is engaged with the catch Z, and the lever O is held in an elevated position,thus holding the flushvalve I) open until the catch Z is moved by the pulling of the chain 0, which occurs when the float-lever h has descended to its lowest limit. The hook at being released the lever 0 falls, the flush-valve closes, and the supply-valve having been opened by the descent of the rising of the float allows the supply-valve to close. It will thus be seen that the flushingva-lve remains open until the amount of w ater determined by the length of the chain 0 has been discharged through the valve. The chain 0 may be lengthened or shortened, so as to vary the amount of water discharged from the tank, according to the requirements.

My improved lock can be attached to many forms of tank and valve mechanism without making any change in the existing construction.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. As an improved article of manufacture, a lock for fiushing-valves, comprising a plate provided with pivot-studs, an angled lever mounted on one of the studs and provided with a long arm and a short hooked arm, and aspring-pressed catch-lever adapted to enfloat-lever, admits water to the tank until the gage the short hooked arm, substantially as herein specified.

2. The combination, with the flush-valve lever and float-lever of a flush-tank, of a lock comprising a plate provided with pivot-studs, an angled lever provided with a long and short arm, a springpressed catch-lever adapted to engage the short arm of the lever, a ring attached to the flush-valve lever of the tank and adapted to receive the long arm of CHARLES SHEPHERD.
